Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Multiple directory traversal vulnerabilities in the iallocator framework in Ganeti 1.2.4 through 1.2.8, 2.0.0 through 2.0.4, and 2.1.0 before 2.1.0~rc2 allow (1) remote attackers to execute arbitrary programs via a crafted external script name supplied through the HTTP remote API (RAPI) and allow (2) local users to execute arbitrary programs and gain privileges via a crafted external script name supplied through a gnt-* command, related to "path sanitization errors."
CWE-22 - Path Traversal
Path traversal (or directory traversal), is a vulnerability that allows malicious users to traverse the server's root directory, gaining access to arbitrary files and folders such as application code & data, back-end credentials, and sensitive operating system files. In the worst-case scenario, an attacker could potentially execute arbitrary files on the server, resulting in a denial of service attack. Such an exploit may severely impact the integrity, confidentiality, and availability of an application.
